My name is Luke, I'll be helping out with your test. Don't worry you'll be up and ready in no time.

Just one quick change:
1) Volume: We need 86-92dB with 89dB being ideal. Your at 79.3 this is what we need to do
Select the whole file in audacity
Go to effects>amplify
Type 10 in the top box
Hit apply

In the future I would recommend turning up the volume slider so that you don't have to amplify every recording that you do
